Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Nearly four decades ago, Roose & Gottlieb (Roose & Gottlieb 1976 Evolution 30, 818–
830.(doi: 10.2307/2407821)) showed that the recently derived allotetraploids Tragopogon …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Whole-genome duplications are radical evolutionary events that have driven speciation and
adaptation in many taxa. Higher-order polyploids have complex histories often including …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Hybridization and polyploidy have been considered as significant evolutionary forces in
adaptation and speciation, especially among plants. Interspecific gene flow generates novel …

Despite their evolutionary relevance, multispecies networks or syngameons are rarely
reported in the literature. Discovering how syngameons form and how they are maintained …

Agricultural selection of desirable traits in domesticated plant and animal species mimics
natural evolutionary selection for ability of species to survive, thrive, and reproduce in the …

The morphological and ecological intermediacy of hybrid taxa has long interested and
challenged fern biologists, resulting in numerous systematic contributions focused on …

Extinct taxa may be detectable if they were ancestors to extant hybrid species, which retain
their genetic signature. In this study, we combined phylogenomics, population genetics and …
